Acaricidal effect of emulsions based on ethophenprox and juvenile hormones on the red chicken mite model

Abstract

 Rational control of the red chicken mite should be based on the selection of means and methods of their use, which provide the best both therapeutic and prophylactic efficacy. 
The aim of our research was to study the acaricidal activity of emulsions based on etofenprox and juvenile hormones on D. gallinae mite. Two series of experiments were carried out. For this, Petri dishes were used, on the bottom of which were placed D. gallinae. The edges of the cup were treated with petroleum jelly in order to limit the mobility of ticks and keep them in the observation area. After that, the emulsions of the preparations were applied directly to the ticks by the method of small-drop spraying.
For further experiments, an MBS-10 microscope was used and observations  were made of the viability of ticks with fixing their 100% death. The test objects were continuously monitored for the first 3 hours, then every hour. After 12 hours of the study, observation and recording of the results occurred every 2 hours. One day after the start of the experiment, the objects in Petri dishes were observed once a day. The control of this experiment was Petri dishes with red chicken mites, treated with a mixture of auxiliary components, used in working  solutions of drugs of this group.
As a result of the studies aimed to study the direct acaricidal action of emulsions based on etofenprox and juvenile hormones, it can be concluded that in a double test, emulsions of drugs in 2% concentration showed the greatest efficiency: etofenprox and smethoprene, etofenprox and pyriproxifen.
